ported on horizontal arms 13, extending from the front of the machine and leaving a space between the housmg and frame m which operate the forming and locking mechanisms.

The housing 1s prolonged toward one slde 1n' tacle is-not shown as to a separate structure,

but it is merely formed by the twoside Walls and theend wall of the housing,- as shown in side view in Fig. 1u at bottom of the sheet and in plan in Fig. 7. i

The section of the belt carries the blank forward on the belt-section 16, where it will rest over'the spaces 12 and will be in-position tov be engaged by the transferring mechanism. A stop to hold the blank within the feed-receptacle and prevent it from bein T carried forward by the moving belt until the proper time is mounted on the housing at the lnner end of the feedreceptacle 14 and consists ofy a pivoted latch 17, adapted to be raised by a trip ona moving part of the mechanism. A fixed stop 18 beyond the belt-section 16 prevents the blank from being carried too far and stops it in correct position for transference. 'lhe belt thus serves to position the blank in front of the horn, ready to be carried to the horn by the transferring mechanism.

The vblaat/c transferring mechanism-The transferring mechanism comprises a lifting device lfor raising the blank from the belt above the housing ,and the presser-block and a pusher for removing the blank from said lifting mechanism.

In' the housing 7 are cut vertical slots in which are adapted to move the lifting-arms 19. (See Figs. 1, 2, and 9.) These arms rest normally. below the feeding-level of the conveyor-belt and when raised engage and lift the blanks, and they have vertical extensions 20, connected to a lower cross-bar 21 of a vertically-reciprteating frame 22, provided with a top cross-bar 22%, which carries a roller 24. lfhe roller 24v bears upon a cam 25, mounted on the main shaft 2, and by this connection the lifting-arms are vertically reciprocated in the housing-slots.

Mounted horizontally in. the main framework is a horizontally-sliding frame 26, (see Figs. 2 and 7,) having a connecting-ann 27 and a cross-bar 2S. llxtending inwardly from the ctmneeting-arin 27 are pusher-arms 2t), |nel'erabl)v in the I'orni ol' depending hooks,

so as to be adapted to strike againstfthc edge of the blank and push the blanks inward. The cross-bar 2.5' ol' the sliding frame is engaged by vertical slotted levers 30, fixed to the end of a shaft 31, journaled in the main frame. )n the shaft 3H is a fixed rocking arm 32, having u loose roller im. adapted to bear upon a cam 34, fixed to the main drivingshaft 2. Coiled springs 35 are connected at their res ective ends to the arms 26 near their rear`en s and the. front part of the main frame and serve to return the sliding frame to its normal position with the pusher-arms at their loutermost point of travel. By the above driving connection of the cam on the main driving-shaft with the sliding frame and by the returnsprings the pusher-arms 29 are horizontally reciproeated in and out just above the level of the.conveyer-belt, whereby they will push the blank from the lifter-arms onto the presser-block.

One of the side arms of the sliding frame 26 is provided witha. pivoted trip 36, having a )in 37, adapted to engage and raise the stoplatch 17 at the end of the receptacle when the sliding frame is carried inward by the cam, 4and thus permit another blank to be fed out of the receptacle by the belt. On the return of the slidin@ pusher-frame the trip yields to the latch and moves past without raising the latter. y

The forming mechanism-The blanks are pushed from the lifter. 'directly .onto the presser-block 38 and are laid transversely thereof in such position that they will extend over folding-wings 39. (See Figs. 6 and 7.) The blanks are limited in their rearward movement by the uprights 40, which form stops and guides, and they rest upon the horizontal lugs41, so as to be sustained without bending above' the Icurved folding-wines. Each winor is of the roper width to iit the blanks and is provide on each side with outside guide-lugs 42, extending above the ends of the wings and adapted -to embrace the ,blanks and to hold them in correct position on the wings. (See Figs. 6, 7, and 10.) Each wing is also provided with a slot 43, extending through its end to enable the wing to pass the fixed lug 41. Each folding-wing is fixed on a shaft 44, journaled in the block and provided with acoiled return-spring 45, having one end bearing against a pin on the shaft and theother end-against the block, so as to tend to hold said wing down in horizontal position and to give it a quick return.

Fixed to the frame of the machine above the block and extending horizontally forward is a forming or supporting horn 'or mandrel 46 of the proper shape to give the desired. form to the box or can to be made. The horn has longitudinal grooves or depressions in the sides and top and bottom in order that the proper bend may be given to the blanks. rlhc block 38 is movable up and down relatively to the horn to carry the blank against the latter, and .to this end the block is provided with depending lugs carrying a pin 47,

to which is pivotally connected theI end of a` lever 4S, pivoted between its ends to a part ol' the l'rnme and having its other end pivoted to n vertieally-reenn't 'ating rod lit. seein-ed to a frame 50, which carries` a roller 51. 'lhis roller bears upon an actuating-cam 52, iixed IOO ITO

tube, and su ply gas and air for the mixture su plied to t 1e heater that serves to heat the so dering-iron. Extending horizontally from the tube 86 are the heaters 90, each comprising a hollow pipe 91, opening at 92 into a housing '93, in whichis removably clamped transversely of the v.housing a soldering-iron 94. The gaseousV mixture is ignited at the opening 92 and the vtla-mejet is coniined Within the housing and projected directly against the soldering-iron. By this construction oi heater the heat may be easily regulated and kept constant without dispersion by exposure to the torce of drafts and the soldering-iron may be easily and quickly removed and attached to the heater. By having the support of the heater serve as a pipe for the gaseous mixture a convenient arrangement is obtained.

A plurality of soldering-irons are provided for the purpose of insuring thoroughness in the melting and application ot' the solder. The iirst of these irons in the direction of movement ot the can-body on the horn is `sprung-pressed pawl provided with mechanism to intermittently move 1t vertically, while the remaining solder- .ing-irons are loosely hung. The pipe-support of the iirst iron is pivotally mounted at 95, and its support is connected to a rod 96, hung on a frame 97 which carries a roller 9S, bearing upon and actuated by a cam 99 on the main driving-shaft 2. This solderingiron is adapted to come in contact with and melt the solder-Wire 100, and to enable the wire to be ied intermittently thereunder is provided with its verticallyreciprocating movement. When the iirst soldering-iron descends, it melts ofi a piece of solder from the solder-wire 100 and the seam ot the can-bod y passing under the iron the solder will be melted and a )plied thereto. A spring or springs 101 hold the. can-body firmly down on the horn and the ends closely together while the solder is being applied.

The solder-wire is ted intermittently l'orward through a tube 102 by means of a feedroller 102%, carrying at one end a ratchetwheel 104, adapted to be actuated by a 105` carried on a rocking frame 106, which is operated by a lever 107.

This lever at its opposite end carries a roller. f

108, that bears on a cam 10U-on the main shaft 2, whereby the lever and rocking arm are rocked to move the ratchet and rotate the 'fecal-wheel. A pressure-roller 110 bears against the wire opliosite the leed-'roller and is yieldingly mounted on the pin ofV a link 111`7 which is pressed against by a spring 1'1 2. A

return-sl'iring is secured at. one end to a iixed part of' the frame and al the other end to a right-angled extension from arm 107.

After the solder has lw.e1i-:n)plie l to the scam the can-body is l'orced along the horn by the succeeding can and passes under the auxiliary soldering-iron.., by. which the john is eifectually sealed. The can-body is then. re-

moved from the horn by any suitable means and is ready to be iianged and headed.

The general operation of the meel:ine-All the operating parts are driven from the main shait-the blank-feeding mechanism by a pulley and belt and the. other mechanisms by cams. The blank is fed from the feed-receptacle by theconveyer-belt S Iupon thc litterarms 1t1,'which are thereupon operated to ,raise the blank above the feed-elninnel, where- !upon the sliding pusher-arms .211 push the blank from the litter onto the presser-block 3S. The block is then lifted by its cam mechanism, so as to carry the blank against the forming-horn 4G, and immediately thereafter the folding-wings 30 are swung upon their iivots by their sliding blocks 56, and the blank is carried up thereby and bent around the horn to vform the can-body, one wing acting in advance of the other7 so as to cause the ends of the blank to overlap. The punch then descends and forms the engaging projections, whereby the ends of the canody are locked firmly together without hooking or doubling the edges, thereby leaving a flat surface, with only two thicknesses at the seam. The can-body so formed and locked is then carried forward onthe horn by the action of the sliding plunger-lingers 79 to the soldering mechanisnnwhere the solder is applied by the irons 94, held in the heaters 90, and then the can-body is removed from the horn.

A locked can-body is shown in Fig. 13. It will he seen that the end portions 113 of the body are locked flat, one upon the other, with their end edges 114 unbent and the side edges 1 15 also in an unbent continuous condition, whereby only two thicknesses oi metal are formed at the edges that have to be turned over when the head is appliedwith the double seam. 4
